過巻検出装置。[Claims for Utility Model Registration] An overwinding detection device for a crane in which a lift block is suspended from the tip of the boom via a wire rope guided by a pulley provided at the tip of the boom, When the weight suspended by the weight suspension rope along the wire rope comes into contact with the hook block as the weight block approaches, the weight suspension rope is suspended. In a crane overwinding detection device that detects an overwinding state of a wire rope by sensing a decrease in force, when the lifting force of the weight lifting rope decreases, the weight lifting rope is activated. An overwinding detection device for a crane, characterized in that a weight lifting rope take-up reel is arranged at one end of the weight lifting rope so as to shorten the length.
